Katsuma Kōgaku (勝間光学, translated as Katsuma Optical Co.) is a Japanese company. It is mentioned by various sources as a binocular maker.
In 1932, a company called Katsuma Kōgaku Kikai Seisakusho (勝間光学機械製作所) is cited together with the measuring instruments branch of Seikōsha as the two founders of Tōkyō Kōgaku (later Topcon), both being dependent of Hattori Tokei-ten.[1] It is unknown if this company is related to the later camera maker.
In the 1950s, a company called Katsuma Kōgaku Kōgyō K.K. (勝間光学工業株式会社)[2] made cameras with the Lyra brand name and used the Terionar brand name for some lenses. These brand names were used by Fuji Kōgaku until 1944, and maybe also after the war.[3] On its Lyra cameras, the company used a KATUMA[4] LYRA logo that was similar in shape to the logo used by Fuji Kōgaku[5]. It is said that the latter company was split into two parts after the war: Taisei Kōki and Katsuma Kōgaku, with the latter one keeping the Lyra brand name.[6]
A related company is Pioneer Camera, which was contemporary with Katsuma and shared the same address.

Notes
- ↑ According to this page of the official Topcon website and to the JCII exhibition catalogue Nihon no kamera o omoshiroku shita kyōshū no burando ten.
- ↑ Its address in 1955 was Tōkyō-to Toshima-ku Ikebukuro 6–1981 (東京都豊島区池袋6の1981).
- ↑ This is suggested by the existence of a version of the Lyra Six with a top housing, having Fujikō markings and typical postwar features, like the synchronized shutter with PC connector.
- ↑ 'Katuma' and 'Katsuma' are two alternative ways to write 勝間 in the Roman alphabet. The latter is closer to the true pronunciation.
- ↑ Another logo has been used on binoculars: KOC (for Katsuma Optical Company) inside a triangle inside a circle.
- ↑ According to Tanaka, p. 44, and this page at Japan Family Camera.
